Modeling an industrial reverse osmosis unit
TLDR
In this paper, a simplified model was used to predict the performance of hollow fiber RO membranes based on the solution-diffusion membrane mass transport model and took into account the effect of the pressure drop in the fiber bore and in fiber bundle, the variation of the bulk solution concentration on the shell side of the fiber bundle and the concentration polarization.About:

Hollow fiber reverse osmosis systems analysis and design
William N. Gill,Bihari Bansal +1 more
TL;DR: In this article, a predictive model of hollow fiber reverse osmosis systems is developed using the equivalent annulus assumption, where the fraction of feed recovered depends on five parameters: pressure, temperature, flow rate, concentration, viscosity of the feed, system length, membrane rejection parameter, and number of fibers.
